Wu Q, et al. - Researchers investigated whether the total dose of exogenous gonadotropins is associated with blastocyst aneuploidy or live-birth rates in PGS cycles in Chinese women. They analyzed data from 1088 PGS cycles and 3219 embryos by array-comparative genomic hybridization (array-CGH). Findings revealed no significant association of the total dose of exogenous gonadotropins with blastocyst aneuploidy or live-birth rates in PGS cycles in these women.
